SPECIFICATION forming part ot Letters Patent No. 657,040, dated August28, 1900.

Application filed October l l 1 8 98- To @ZZ who/1t it 71mg/ concern,.-

Be it known that I, ROSWELL I-I. ST. JOHN, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Type-BarMachines; and I do declare that the following is a full, clear, andexact description of theinvention, which will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to improvements in type-bar machines; and theinvention consists more particularly in distributing mechanism for thematrices, but embodies a few other features as well, all substantiallyas shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis an end elevation of thedistributing mechanism mounted on the frame of a type-bar machine inwhich matrices are used to produce the type-bars; but only such parts asdeliver the matrices in bulk to the distributer and from there singly tothe magazines are shown in this View and more is not required for thepurposes of this description. Fig. 2 is alongitudinal sectionalelevation on line 2 2 of Fig. e, enlarged in respect to Fig. l, andshowing more especially the receiving-box, feederchain, and distributingor carrier chain, the distributing-chain being broken away at its centerto bring the ends within the limits of the drawings and. showing thechain at the left with some of its parts removed to more clearlydisclose the lugs for carrying the matrices forward. Fig. 3 is across-section of the receiving-box on line 3 3 ofV Figs. 2 and 4,showing especially the grooved cam and plunger device for feeding singlematrices successively to the feeder-chain. Fig. 4 is a plan sectionlooking down from a line corresponding to 4 et of Fig. 2. Fig. 5 is across-section of the distributing-box and a longitudinal sectionalelevation of a single magazine-channel or matrix-receptacle, the Viewbeing taken on a line corresponding to line 5 5 of Fig. 4 looking to theleft. A matrix is shown in edge elevation as being discharged by thespringbolt on the distributing or carrier chain, and another matrix justthis side is shown in perspective dropping into its channel or maga-Serial No. 693,230. (No model.)

zine. In fact, however, the said matrix sustains the same edgewiserelation in all its positions as it travels into the magazine. Fig. 6 isa cross-section and perspective elevation more particularly of one sideofthe distributing-box and showingalso a section of the leftdistributing or carrier chain and a single matrix in position to becarried forward to its drop. Fig. 7 is a sectional and perspectivedetail of the right or opposite side to that shown in Fig. 6 of thedistributing-box and carrier-chain, with a single matrix in position tobe discharged into its receptacle or magazine, presumably the same asshown in Fig. 6. Fig. 8 is a detail perspective View of the gage in thematrix-receiving box preparatory to distributing the matrices, but whichallows but one matrix at a time to be discharged from said box. Fig. 9is a perspective view of the distributing-box and the magazinechannelsupports, the receiving-box being removed and showing thedistributing-box in section. Fig. l0 is a perspective View of a completemagazine-frame, and Fig. l1 is a perspective view of the bolts forlocking the said frame into place.

The distributing mechanism thus shown and hereinafter more fullydescribed is designed more especially for distributing matrices intype-bar or linotype machines; but with very slight modifications inregard to proportions and the like the same construction can be used fordistributing type.

In the type-bar machine in which the presentinvention is used thepractice is to assemble a number of matrices of like character inmagazine-channels 60, from which they are released one at a time, as maybe required, for composing a line of type. After the matrices have beenused to produce a type-bar they are all promptly returned by automaticarrangements to their respective magazinechannels; but before this canbe done each matrix must be separated or assorted from the others andthen individually distributed into its own channel.

In Fig. l a double-threaded screw 3 is shown, carrying a traveling box4, which deposits its load of matrices 5, presumably a complete line,into a transferring device 6, which in turn deposits the entire loadinto IOO vss

the distributing-box 2. A detail description ofthe matrix-bulk-carryingdevices is not entered into in this case, as the exact construction ofthe same is not deemed material to the distributing device, which moreparticularly constitutes the invention in hand. In fact the matrices canbe deposited into the distributing-box 2 by any suitable means or evenby hand, if desired.

The matrices 5 are all of uniform size and shape except in thickness,which depends on the size of the character thereon and such modicationsof detail as may be required to cause each matrix to definitely nd itsown channel. All alike have a long body portion or shank 7 and aT-shaped head at one end and a rounded extremity at the other end.Between these ends, and particularly toward the smaller end b, thematrices are formed with notches or recesses 9 in their edges, which arealike as to all characters of the same kind, but unlike as to all theothers, so that only like characters will come together. How this worksout is plainly seen in Fig. 6, where each successive dropping-space isunlike all the others, and hence each matrix can only drop where itbelongs. This appears clear as we further examine the distributing-box,which is provided with alternate inward projections 12 and openings 13,and each projection 12 has one or more lugs 14 extending into and partlyacross the said opening at one or both sides. These lugs are so arrangedand distributed in each and every opening 13 as to be distinctlydifferent from all the others, and so that all the other matrices thanthose intended for it will slide over and along just as if they werepassing over a continuously-smooth surface. ln practice about ninetydierent characters are used, and so ninety openings 13 are `needed toaccommodate them, and no two a-re alike as to their notches 9, as no twoarrangements of the corresponding lugs 14 are alike in position orspace. I

Returning now to the distributing-box 2, (shown in plan, Fig. 4, and insection, Fig. 3,) the said box, it will be seen, is provided with anopening c, extending from top to bottom of about the width of thematrix, and the matv rices 5 lie hat one upon the other between thewalls 15 and 16 at its sides. The T-head of the matrix rests itsextremities Within the vertical channel 17 at each side of the walls 1G,and this channel is open at the top, but closed at the bottom, Where aslight ledge 18 is formed to hold the matrices up untilthey are pushedolf by the plunger 19. (Shown at the left in Fig. 3.) This plunger actsaxially on the matrix and pushes it far enough endwise to vdisengage itat both ends and cause it to drop. The channel 20, in which the T of thematrix rests, is enlarged at the bottom at a point opposite ledges 18,and this allows the side movement necessary for the matrix-4 arms toclear the ledge 18 and drop down upon thebase-plate 10. Now as thematrices y on the ledge 18.

lbegin at said plate.

vary in thickness according to the character or letter upon the edge at21 provision is made to accommodate the varyin g thicknesses thereof, soas to allow only one matrix at a time to be pushed and dropped out ofthe box by plunger 19. To this end all the thicker or heavier matriceshave a groove or channel 22 in their face at the T end, and this grooveis cut down a certain depth in all that are cut, so as to leave acertain thickness of metal corresponding to the depth of the thinnestmatrix. Opposite this groove 22 is a thin inwardly-projecting tin 23,which is part of the vertical rod or bar 24, adjustably held within theend of the box by set-screws or other suitable means. The thinnestmatrices resting upon ledges 18 are free to slide under the n 23, andthus drop down free when the arms of the head 8 ride beyond the edge ofledges 18; but the matrices above abut against the front edge 25 of thepin and are prevented from feeding out by frictional contact with thedischarging matrix. As this adjustment of iin is necessarily very ne andfixed when made, it will be seen that the thicker matrices would notpass under the tin when it is down in working position, and so thegrooves 22 are cut deep enough and long enough to allow any-sized matrixto be discharged, the fin fitting freely in the groove, but stillserving its purpose of holding back the upper matrices, whether thin orthick, and operating on all alike.

rlhe plunger 19 is carried back and forth with evenly-timed movements bymeans of a roller 26, fixed on its bottom and traveling in the sinuouschannel 27 in the periphery of the cam roller or wheel 28. As thematrices feed down by gravity, they first rest at their small end on theend 29 of the plunger and then dropdown upon the ledge 30 as the plungeris withdrawn. At the other end they rest When the plunger comes forwardagain, the-end 29 thereof pushes the lower matrix off both ledges 30 and18, and the said matrix then falls upon the base-plate 10, where thefeeder-chains 3l engagel and move it forward to be engaged by thecarrierchains 32, as most clearly seen in Fig. 2.

The plate 10 is a short plate between 'the box 2 and the distributingcarrier-chains and is formed on each side with a slot, through which theengaging spurs 31a of the feederchains 31 project and travel. Said slotscommence just outside box 2 and continue to near the end of plate 10, asseen in Fig. 4. The carrying-ledge 59 for the heads of the matrices andthe projections 12 at the opposite side The chains'31 are arranged oneat each side and are mounted upon flat-faced gears 35, having [langes 36to `keep the cha-ins in alinement. Said gears are supported upon shafts33 and 34, Fig. 2, journaled in bearings 38 and 38', which are hung fromthe bottom of the base-plate. Set-screws 37 furnish means for tighteningor loosening the chains 31 by moving the bearings 38 back IOO IIO

or forth, and a gear V39 upon one end of shaft 33, Fig. 4, transmits thepower from a gear 40 upon shaft 41, which carries the spurwheels 42 forthe carrier-chains 32.

The carrier-chains 32 in a full-sized machine have a straight travel ofsix feet, more or less, and the distance is suiiicient in any case tocover the space required for, say, ninety diiferent matrices andcorresponding magazine-channels. At the other side or end, opposite thedistributing-box 2 and wheels 42, the chains pass around the fiat-facedspurrollers 43, which are mounted on the crossshaft 44, Fig. 2. Theshaft 44 is supported in bearings 45 on the distributing-trough 11, anda pulley 46 furnishes the means through which the power is applied tooperate all of said parts. Gearing can be substituted for the pulley, ifdesired. The long line of travel of the matrix-carrying chains makes itimperative that some means for guiding and keeping the chains inalinement be used, and to this end the sides 47 of the distributingbox11 are constructed with channels having confining-ledges 49 and 50 atright angles to each other, and each link 32n :is made with a channel orgroove 32h, engaging over ledge 49. Rollers 51, Fig. 7, journaled withineach link, ride between ledges 49 and 50 and take the wear, as well asform an antifriction-bearing for said links. The links are pivotallyconnected together through overlapping ears 52 by pins Each link has acentral transverse groove 54 in its top or outer surface, into which theteeth or spurs on the rollers 42 and 43 engage as the chains pass aroundthe same. Each link 32a of the carrier-chains 32 also has a projectinglug 32c at what becomes its forward or engaging edge when in action andreaching down to near the baseplate when the chains are in engagementwith the matrices, and these lugs gather up and carry along the matricesas they are fed to the carrier-chains by the feeder-chains fromdistributingbox 2. The feeder-chains 3l and carrier-chains 32 are timedto move at the same rate of speed, and the matrices are delivered singlyand in rapid succession one after the other until the supply from box 2is eX- hausted. Now in order that there may be no delay in dischargingthe matrices from the can rier as each one comes to its drop the linksof chain 32, operating at the heads of the matrices, are each providedwith a spring-pressed T-shaped presser 55, having its stem d supportedin ears on the front of thelink and with an interposed springe to bearthe presser down to acting position. The engaging edge of the presser isstraight lengthwise, so as to bear fiat on the matrix, and is cut awayor reduced back of its point of immediate engagement, so as to carry thepoint of engagement as .far as possible from the fulcrum ot' the matrixon ledge 59. Then as the matrix reaches its opening 13 and drops at thatend the presser will exert itself at once to effect one instant Swing ofthe matrix into the mouth of its lthe head a.

channel. Obviously if the spring be at all strong Ithe drop or turn fromfirst position (seen in Fig. 5) to the next and down into thebank-channel will occur instantly and before the presser can have timeto travel olf The narrow ledge 59 runs the entire length of thecarrierchains, and the heads of the matrices rest upon it, while theother ends are supported by the projections 12 andlugs 14, as alreadydescribed.

The magazine-channels 60 are arranged side by side in close proximityand are alike, so that the description of one will answer for all. Eachlchannel extends inward a short distance from ledge 59 and is open atits top and edge to receive the matrix when thrown down by thepresser-foot 55. Inner walls 61, having their Lipper edges curved andinclined inward, serve as guides and supports for the matrices, theT-shapcd heads of which drop into the open passage-ways 62 and slidedown into the channel (JO. In Fig. 5 one of these guide-,walls 61 isremoved while the matrix shown is engaged over the remaining wall. Assoon as a matrix is released at its small end it swings in between thewalls 61, and the hooks on the T-head cannot fail to engage as they aredesigned to. To insure the transverse alinement of the matrices as theyapproach the carrier, a spring-pressed bar 63 is pivoted to the wall ofthe distributing-box 2, and this bar is centrally` located between thetwo feeder-chains 3l and serves to retard the forward movement of thematrix sufliciently to even its ends. This is not necessaryin allcases,but is a good precaution.

The plunger 19, before described, is supported within a sliding bar 295Land the roller 26 is mounted on this bar. A spring 29.1, bearingagainsta shoulder within the bar and against a shoulder on the plunger,serves to prevent the plunger from jamming a matrix if it be bent orslightly defective and should stick in the distributing-box. Then againthe action of the spring on the plunger serves to discharge the matricesevenly and quickly without hammering or mutilating them.

When the machine is in active use, the feeder and carrier chains 31 and32, respectively, with their associate mechanism, are constantly inmotion, whether matrices are or are not within the feed-box.2. As soonas a load of matrices is dumped into the said box the plunger 19, beingin action, at once begins the work of discharge therefrom one at a time,which drop first upon the plate 10 and between two spurs of thefeeder-chains 3l. The

travel of all the released matrices is forward have arranged a plate 64with a curved edge i 65 to engage the presser-feet 55 andkeep ICO IIO

them off the heads of the matrices until they are completely engaged atboth ends by the chains 82. Then each presser-foot 55 rides easily offthe curved edge 65 and onto its matrix and remains there till the matrixreaches its drop. A short extending pin 66 on each bolt engages thisedge eccentric 65 before the roller 4t2 makes a third of a revolutionand then continuing each bolt is pressed back by the pin riding on theeccentric until the extremity 67 is reached, where the pin then goesfree and allows the bolt to engage the matrix, as described. As thematrices travel forward at a comparatively-slow speed, they are alldistributed before they reach the outer extremity of the trough, so thatnone. are carried over. They may go to different channels, or severalmay successively drop into the same channel, and the carrier will asreadily drop all into one channel as into several if they all be of thesame kind. This is mentioned to show the rapidity with which thematrices are discharged from the carrier. Hence, also, the distributercan easily take care of the matrices as they come along however rapidlythe machine may be operated, and eight to ten lines can easily bedistributed in a minute and not tax the distributer for speed oraccuracv.

All the magazine-channels are built into a single supporting-frame, sothat the frame and all are removable at once from the machine. Thecomplete frame and its magazinechannels are shown together and alone inFig. 10 and in position on the frame at their top in Fig. 5, while theirWhole support is plain in Fig. 9. The lower support 70 has asemicircular groove lengthwise, and the lower bar of the frame H has acorresponding groove. Hence when the said frame H is seated above andbelow, as in Fig. l, for use the half-length bolts g are inserted in thechannel aforesaid between frame H and rest 70, and as such they serve toaline the frame and secure it in working position. As eachmagazine-frame carries its own 1natrices,there can be an entire changeof font of type in the brief time required to make this exchange. Thiscan be done also while the machine is in operation.

The frame itself, H, which carries the magazine-channels, is a mereskeleton, and the channels are each and all rigidly but removablyattached thereto. Hence when a frame H is removed the channels are alllifted off with it and so, also, when they are put back. The timerequired for changing the magazinechannels or fo'unts is socomparatively brief that in newspaper or other work where it is desiredto use a different font for a quotation or the like it can be done andnot cause any appreciable delay.

Referring to Fig. 5, it will be noticed that after the matrix-bar dropsfrom the ledge at its head end it drops onto the inclined shoulder h,which produces just enough detention or delay in the dropping at thisend to insure an unerring lodgment of the matrices in their channels andwithout any danger that they will get away.
